I am pretty sure that this is the card that is making the trouble here. HBM2 on it is like 12-14C hotter than the core, unlike any other cards I have where the difference is smaller ...

Any idea how to fight it? Its already undervolted, and fans are running quite high. Current room temp is around 18C, so can't really improve much on that front.

Would any additional fans do any good? Like case fans from both sides blowing into it or something?
Any other ideas?

Are you 100% sure that the card is undervolted? Almost every time I quit xmr-stak-amd the driver glitches and resets one of my cards to the default voltages and also ramps the fan down to 400rpm. That is on both of my rigs (1 card on each rig resets, I think it is always the same one). I just restart, run mythic's driver reset bat, run hellae's registry file, restart, run mythic again, reset voltages to manual and fans to 3000 and then it is fixed.
I still do get some GPU COMPUTE ERRORS but it is more like 10 per week, mostly on one of the two rigs. Each rig is running 4 vega 64s.
